Interpretation Introduction
Interpretation:
The compounds A and B that are isomeric
Concept introduction:
Spectroscopy is a method that is used to identify the structure of the molecule. It is based on the interactions between matter and
Proton NMR spectroscopy identifies the number of hydrogen atoms present in a molecule and the nature of the functional group.
The value of chemical peaks depends upon the chemical environment around the hydrogen atom.

Aniline (conjugate acid pKa 4.63) is a considerably stronger base than diphenylamine (pKa 0.79). Account for these marked differences.
Calculate the percentage of free acid for (a) phenobarbital (it is an acid with pKa = 7.40) and (b) hexobarbital (also an acid with pKa = 8.4) at the physiological condition of pH 7.4.
How does the 13C NMR resonance of the thiol/thione carbon compare between the free HOPTO ligand and the complexed ligand in Pd(mpo)2? Propose a reason for the difference and why this resonance is shifted more than the others.
